The stars are what they are irrespective of the opinions expressed in the field of cosmology. It amazes me that pronouncements are made about distant objects with such unshakeable certainty when in the cold light of day the reach of verifiable science is not nearly so self-assured. I am reminded of Al Gore’s brazen assertion that “the science is settled” in climatology, a field which rivals cosmology in chaotic outcomes. The most daunting challenge facing space science is that of scale. In an infinite Universe, we will always be infinitely more ignorant than we are wise. In my view, we have more than enough to keep us occupied in the celestial neighbourhood, and would do well to take things one step at a time. Compare the science proposed in Hannes Alfven and Gustav Arrhenius “The Evolution of the Solar System” with Alan Guth’s pronouncements on Inflation Theory, or George Smoot’s take on the CMB, or indeed, even the core principles of General Relativity and Quantum Mechanics. The question I like to ask myself is “How does this theory connect to observed reality?” In a sitting room conversation with Halton Arp a few years ago, the late Fred Hoyle said, “I suppose that in the end, Chip, the Universe will have its say.”
The shocking reality is that research is done for money, not in pursuit of truth. The Theory of Everything which will no doubt be pronounced by high-energy physicists in the not-too-distant future will, I fear, be a set of mathematical sentences so arcane that none could render them false, and they would in any event be based upon experiments that have no intrinsic meaning discernable to scientists in more general research. In short, the magic will be witnessed and explained exclusively by the conjurors themselves, and we will have to decide on blind faith alone whether we believe them or not. What really happens in the Large Hadron Collider remains for the vast majority of us nothing more than conjecture, and I suppose their conclusions are inevitably going to form the basis of a large chunk (or even all) of cosmology. Astronomers will play no part in where astronomy is going.
